Szymekk ransomware is the threat that derives from the CobraLocker ransomware family. It’s a cryptovirus that, upon successful infection, encrypts users’ computer data, except non-system files, and demands for a ransom to receive a private decoding tool/key. After successful encryption of computer data, most ransomware places ransom notes as .txt files on the desktop and affected folders. Shymekk virus operates differently – it locks the computer screen and shows the ransom message in it. The message itself is very short. Cybercriminals[1] just inform the victim that their device is encrypted and provide an email address (Cobra_Locker@protonmail.com), urging the users to contact them to receive further details.
